Chapter 1 Product Overview

1.1 Introduction

H3C S5500-EI Series Ethernet Switches (hereinafter referred to as the S5500-EI series)

are Gigabit Ethernet switching products developed by Hangzhou H3C Technologies

Co., Ltd. (hereinafter referred to as H3C). The S5500-EI series support diversified

service features, IPv6 forwarding, and routing function, and provide 10GE extended

module slots. Through the H3C proprietary cluster management, you can streamline

network management. The S5500-EI series are designed to operate at the

convergence or access layer of enterprise networks and metropolitan area networks

(MANs). The S5500-EI series support the IPv4/IPv6 dual stack and can also be used

for connecting server groups in data centers.

Table 1-1 lists the models of the S5500-EI series.

Together with an auto-sensing 10/100/1000BASE-T Ethernet port, each 1000Base-X

SFP port forms a Combo port. For each Combo port, either the SFP port or the

auto-sensing 10/100/1000BASE-T Ethernet port can be used at a time. For the

mapping between the two ports forming a Combo port, refer to

Table 1-2.
